Some lecture notes can be obtained by clicking on the lecture titles
(for ASCII) or the PostScript links
(which save paper).
Please understand that they are lecture notes,
and that they were written so that I would have something to say in class.
I write them for me, not you,
and I make them available as a courtesy to you.
Do not be surprised if they say the same thing I said in class;
I edit them after class to make sure of this.
If I receive any more complaints that
my lectures and lecture notes do not differ,
I will stop making lecture notes available.
For related reasons, I will not make the lecture notes for a class available
until after that class.
